Preheat oven to a grill function (remember not all ovens are born equal!!) to around 250ºC if possible. Line a baking tray with paper and place the chiles, capsicum, garlic and tomatoes onto the tray. Roast until skins are charred and softened. Remove from the oven and cover whole tray with foil until food has cooled enough to handle.
Meanwhile, place remaining ingredients into Thermo bowl and chop 4 sec/speed 5. Scrape down sides of bowl and saute 5 min/Varoma/speed 2.
Place all roasted veggies including juice and skins into Thermo bowl and blitz 10 sec/speed 10. Pour into sterlized jars and seal. Use as suggested or just as a spicy version of tomato sauce, on anything you may use tomato sauce on….or chilli sauce for that matter.
